Function

System information
This device is a product of the KNX system and corresponds to the KNX guidelines. Detailed specialized knowledge obtained from KNX training courses
is required for understanding. The planning, install-lation and commissioning are carried out with the help of KNX-certifi ed software.

System start-up
The function of the device is software-dependent. The software is to be taken from the product database. You can fi nd the latest version of the product database, technical descriptions as well as conversion and additional support programs on our website.

Easy start-up
The function of the device is confi guration-dependent. The confi guration can also be done using devices developed specially for simple setting and start- up.
This type of confi guration is only possible with devices of the easy system. Easy stands for easy, visually supported start-up. Preconfi guard standard functions are assigned to the in/outputs by means of a service module.

Correct use

• Measurement and evaluation of the weather data: precipitation, temperature, wind speed, twilight and brightness
• Horizontal installation on the outside of buildings (fi gure 3), preferably in the roof and facade area  Plocation. Variations to other weather services–  e.g. through local turbulence or areas with build-ups of air – are possible.

Product characteristics

• Integrated KNX bus coupling and data process-ing unit
•  Integrated GPS antenna
• Command for ON/OFF switch outputs :
  • an output for day/night information with an  adjustable threshold of 5 to 50 lux;
  • alarm outputs: 1 rain alarm, 1 temperature alarm with an adjustable threshold of -20°C to + 50°C and 3 wind alarms that can be adjusted from 10 to 100 km/h.
• Reception of date, time and location data (installation location) via GPS signal
• convenient shade and heat protection functions (with position tracking and horizontal sun track-ing) for up to four building facades through the use of a brightness sensor and accurate solar positioning calculations

GPS data, date, time
The date, time and exact location coordinates
of the weather station are received via the GPS signal. Date and time can also be received via the KNX bus and may be used as master or slave depending on ETS programming.
This information is required to control the automat-ic changeover for daylight savings time.
If programmed, the device receives the date and time during fi rst start-up via the KNX bus until the fi rst GPS signal is received.
If the device is operated in a country that does  not require changes to be made for daylight savings time, the Summer time off set in min-utes should be set to zero..

Simulation function (only in ETS)
Only available using the ETS confi guration. It tests the product programming independently of weath-er conditions. It uses dedicated KNX objects to simulate weather conditions and solar positioning. This simulation checks that the alarm is triggered when the thresholds are exceeded and that the heat protection, collection and shade functions work.

Maintaining the device
The weather station should be checked for soiling at regular intervals – at least twice a year – and cleaned if necessary.
Heavy soiling can make it impossible to calculate wind speed correctly, cause the precipitation sensor (1) to display a permanent precipitation message, or prevent the bright-ness sensor (2) from detecting any sunlight.

Information for electricians

Installation and electrical connection
Touching live parts in the installation environment can result in an electric shock.
The device could get damaged.
Disconnect the connecting cables before working on the device and cover all live parts in the area!

Selecting installation location
Select the assembly location so that wind, precipitation and sun can be detected by the sensors without impedance:

• Avoid infl uences by obstacles or shadings such as facades, roofs or trees
• Do not install underneath construction components that can delay precipitation from reaching the sensor
• Avoid infl uences on the GPS signal caused by magnetic fi elds, transmitters and interference fi elds for electrical devices, such as fl fluorescent lamps, neon signs and switching power supply units
• Do not mount in the vicinity of chimneys or oth-er gas or ventilation systems
• Do not mount in the vicinity of radio transmitter systems
• A space of at least 60 cm must be left free be-low, to the side and to the front to guarantee correct wind measurements and to ensure the device does not become covered in snow
• Install on vertical walls (fi gure 2) or on a mast (fi gure 5, right)
  Select the mounting location so that the weather station will always be accessible for maintenance purposes.

Aligning the device
To measure the brightness accurately, align the weather station in such way that the brightness/twilight sensor (2) faces south.

• Use a compass to align the device to the south (fi gure 3).
  An incorrect alignment may infl uence the mea- sured values of the brightness sensor..
  In some cases, it may be appropriate to align  the device in a direction other than south to ac-commodate existing walls or other geographi-cal factors.

• Use a spirit level to align the device horizontally (fi gure 3). 

Connecting and installing the device

Observe the layout requirements for SELV installations.
To avoid EMC interference, do not install input  Pcables parallel to mains cables.
The weather station is supplied complete with a wall/mast fi xing (6). This is locked into place on the rear of the device upon delivery (fi gure 4).
Optional holders are available for mounting the device on walls, masts or brackets (see acces-sories).

• Carefully loosen the wall/mast fi xing (6) from the detent mechanism using a screwdriver and slide it downwards to remove (fi gure 4).

• Use two screws to attach the fi xing vertically to a wall or use the accompanying cable ties to attach it to a mast.
  When doing so, please ensure that:

  • In the case of wall mounting, the smooth side lies against the wall and the crescent-shaped bar (7) is at the top (fi gure 5, left).
  • In the case of mast mounting, the curved side lies against the mast and the crescent-shaped bar (7) is at the bottom (fi gure 5, right).
    The distance between the holes and the mea-surements for aligning them can be found in the accompanying drilling plan.

• Gently pull the cover apart from the detent mechanisms (9) at the sides and remove the cover (8) from the bottom part of the housing (3).
  Take care when opening the weather station. The precipitation sensor in the cover and the printed circuit board in the bottom part of the housing are connected by a cable.

• Programming button and programming LED

• GPS antenna  ****

  • Place cover (8) onto the bottom part of the housing (3) and push carefully until it engages audibly.
  • Slide the weather station into the mounted
    fi xing from above. Ensure that the pins for the wall/mast fi xing engage audibly into the guides for the bottom part of the housing (fi gure 8).

• The weather station is ready for operation.
  The wind measured value and all wind switching outputs cannot be outputted until 60 seconds after the auxiliary voltage has been applied.
  in the event of any damage, take the device out of operation immediately and safeguard against turning back on.
  Dismantling the device
  Opening the device may allow moisture to enter the interior.
  This would result in damage to the electronics.
  Do not open the device in the event of precipitation and be sure to remove any external moisture from the device with a dry cloth before attempting to disassemble.

• Pull upwards against the resistance created by the detent mechanism to remove the device from the wall/mast fi xing from above.

• Gently pull the cover apart from the detent mechanisms (9) at the sides and remove the cover (8) from the bottom part of the housing (3).

• Disconnect bus line (11) and auxiliary voltage (10).
